Quote #4
hours of weariness (27)
Like in the opening lines, the speaker emphasizes the period of time that has elapsed. The "hours" could have "weari[ed]," or tired him out, either mentally or physically. Spending any time at all in the "din/ Of towns and cities" seems to take quite the toll on the speaker.
Quote #5
when the fretful stir
Unprofitable, and the fever of the world,
Have hung upon the beatings of my heart— (52-54)
The "fretful stir," or anxious bustle of the city is described as "unprofitable." The speaker uses a word that suggests that the hubbub in the city is useless in some absolute, quantifiable way. "The fever of the world" also suggests that the city makes people feverish, or agitated. The place has a physical effect on the speaker. The sense of oppression and anxiety "hung upon the beatings of [his] heart."
